I spent more time then I'd like to admit scouring the market place and asking around for recommendations when trying to make an avatar that fit the "nardoragon" style which is popular in vrchat, but eventually I just decided that I'd be better off actually learning how to do things myself. I can get a model easy, and it's already rigged though from what I can gather that rigging will not work for second life. Where should I start with trying to learn how to import my own avatar into second life? I'd like for it to be decent quality and I'm prepared to put a substantial amount of work into it if need be. The baseline I'd like to achieve is moving eyes, mouth, tail, and HUDs to adjust those features (ie: being able to raise and lower eye lids and open/close the mouth) but before I commit to anything monetarily I'd like to know it's at least doable. Eventually I'd like to be doing my own texturing and modeling but I need to start somewhere and I feel like rigging and importing a pre existing model is a good place to start.
Any pointers would be massively appreciated, be it communities that can help or tips and tricks.
